California Bureau of Unclaimed PropertyFrom the State of California&quo;s Unclaimed Property (UCP) Program web site:
---search for record of "property you may have lost or forgotten"
(property includes bank accounts, security box contents, stocks, royalty payment, insurance policies, etc., but not real estate)
---obtain a form to file a claim for unclaimed property

Unclaimed properties are "any funds or intangible personal property that have remained unclaimed by the owner for a certain number of years. ... Unclaimed property takes many forms. Forgotten savings and checking accounts, uncashed payroll checks, stock, and utility and rental deposits are examples. Also, retirement benefits, safe deposit box contents, tax and fee refunds, credit balances, old life insurance policies, accident benefits and more."

This site is maintained by NAUPA (National Association of Unclaimed Property Administrators), state officials charged with the responsibility of collecting and reuniting lost owners with their unclaimed property.
